Answers: that you need a nap?
your eyes start shutting down...you start thinking about the warmth of your bed and a hot cuppa milk... you drift away into a sea of dreams and thats when you know... =)
General feeling of fatigue and the inability to focus on simple tasks.
I'll be grumpy:)
i have been told that if you tend to stare at one thing for more than 20 seconds that means you are tired and should rest....
Can't keep my eyes open.
oh, I need one everyday...I just know.
I get tired and yawn or I stay up all night and just know I need sleep .....Sometimes I just look like I need one and my eyes and bones are tired....
Very heavy eye lids - happens a lot just after lunch at work.
There's no way to tell with me, I don't usually take naps. They don't serve me well...
